The minimum sound pressure level required for detection of a response was determined using a 5 dB minimum step size.
From the numerical results it is observed that the minimum sound pressure level for NACA 65-010 is 65.4 dB(A).
It is found that irrespective of the shape of the orifice, the synthetic jet generates the minimum sound pressure level when operated at its resonance frequency, which is equal to the diaphragm frequency in the present case.
Design of duct networks is challenging because the design should consider the required flow rate, acceptable noise levels, and minimum pressure drop to achieve optimum performance.
Results: Pregnancy decreased mean arterial pressure, increased heart rate, and modified the reflex by shifting the mean arterial pressure heart rate relationship to a lower pressure level, by increasing minimum heart rate, and by decreasing baroreflex gain (P <.05).
At halftime of the AFC Championship game against the Indianapolis Colts on January 18 , 2015 officials measured and found that all 11 of the Patriots game balls were below the minimum 12.5 pounds per square inch pressure level.
Goldberg also points out that the Patriots weren't the only ones with footballs below the minimum 12.5-pounds-per-square-inch air pressure level required by the NFL.
From the start to the end of the storm we recorded the 6-hourly: (1) time; (2) latitude; and (3) longitude of the minimum pressure cell; and (4) the minimum mean sea level pressure.
The delay time was calculated as the time between the start of inspiration and minimum airway pressure, and the inspiratory trigger pressure was defined as the most negative pressure level.
Under the "newly created" circumstances of a fully recruited lung, it is essential to determine and maintain an end-expiratory pressure level above the closing pressure of the newly recruited lung and use the minimum possible ΔP.
